PAPER SELECTION 

3.3. Selecting the right paper 

IMPORTANT: The UF-1 is not designed for use with envelopes. Never attempt to feed 
envelopes using the UF-1. 

Printer printing is a process involving light beam, electrostatic discharge, toner, and heat. 
In addition, as the paper passes through the printer it undergoes considerable sliding, bend- 
ing, and twisting motions. A high- quality printing paper matching the requirements with- 
stands all these stresses, enabling the paper feeder and the printer to turn out clean, crisp 
printed copy consistently. 

Remember that all paper is not the same. Some of the factors to consider when selecting pa- 
per for use with the paper feeder are as follows: 

CONDITION OF THE PAPER 

Avoid using paper that is bent at the edges, curled, dirty, torn, or contaminated with lint, 
clay, or paper shreds. 

Use of paper in these conditions can lead to illegible printing, misfeeding, and paper jams, 
and can shorten the life of the paper feeder and the printer. In particular, avoid using paper 
with a surface coating or other surface treatment. The paper should have as smooth and 
even a surface as possible. 

PAPER SIZE 
The universal feeder accommodates the following paper sizes. 

♦ A5 to A4 sizes 

♦ Letter size 

♦ Executive size 

♦ B5 size 

Since the printer does not recognize the size of the paper currently loaded in the universal 
feeder, it assumes that all paper fed from the universal feeder is Letter size (8-172 by 11 
inches). You can use the SPSZ (Set Paper SiZe) command of the PRESCRIBE command lan- 
guage to tell the printer the size of the paper. Refer to the printer's User's Manual. 



3—5 



PAPER SELECTION 



SMOOTHNESS 



The paper should have a smooth, uncoated surface. Paper with a rough or sandy surface can 
cause voids m the printed output. Paper that is too smooth, however, can cause multiple 
feeding and fogging problems. (Fogging is a gray background effect.) 

BASIS WEIGHT 

Basis weight is the weight of a standard quantity of paper. In the traditional system the 
standard quantity is a ream consisting of 500 sheets measuring 17 x 22 inches each. In the 
metric system the standard quantity is 1 square meter. 

Paper that is too light or too heavy can cause misfeeding, jams, and premature wear of the 
paper feeder and the printer. Uneven paper weight can cause multiple feeds print defects 
poor toner fusing, blurring, and other print quality problems. The proper weight is 64 to 151 
g/m (17 to 40 lbs/ream). 

MOISTURE CONTENT 

Moisture content is defined- as the percent ratio of moisture to the dry mass of the paper 
Moisture can affect the paper's appearance, feedability, curl, electrostatic properties and 
toner fusing characteristics. 

The moisture content of the paper varies with the relative humidity in the room When the 
relative humidity is high and the paper absorbs moisture, the paper edges expand becoming 
wavy m appearance. When the relative humidity is low and paper loses moisture, the edges 
shrink and tighten, and print contrast may suffer. 

Wavy or tight edges can cause misfeeding and alignment anomalies. The moisture content 
of the paper should be 4% to 6%. 

To ensure the proper moisture content it is important to store the paper in a controlled en- 
vironment. Some tips on moisture control are: 

♦ Store paper in a cool, dry location. 

♦ Keep the paper in its wrapping as long as possible. Rewrap paper that is 
not in use. 

♦ Store paper in its original carton. Place a pallet etc. under the carton to 
separate it from the floor. 



3—6 



PAPER SELECTION 

♦ After removing paper from storage, let it stand in the same room as the 
printer for 48 hours before use. 

♦ Avoid leaving paper where it is exposed to heat, sunlight, or damp. 

3.3.1. Paper storage 

When the paper feeder is not to be used for a long time of period, the paper must be re- 
moved from the feeder and wrapped in moisture-proof paper for storage.

If the jammed paper is inside the printer, turn off the power and remove the universal 
feeder. Then open the printer's paper feed unit and remove the jammed paper. 

If you clear the jam without turning off the power, you can reset the paper jam error by 
opening and dosing the printer's top cover or the paper feed unit. Otherwise, the errors re- 
set when you turn on the power. 

Reinstall the universal feeder, if necessary, then raise the weight roller to where it locks in 
he up position, load paper mto the feeder, and gently lower the weight roller The printer 
then warms up and goes on-line. Printing resumes automatically if you cleared the jam 
without turnmg off the power. Otherwise, you may need to re-start the print job '
